On a corner lot in Leimert Park in dusty South Los Angeles, not far from Obama and Crenshaw Boulevards, sits a curiosity that’s wildly different from all the neighboring grassy yards. Abundant and lush, it looks like a mash-up between a country idyll and something dreamed up by Dr. Seuss. Run by a gardening wizard named Jamiah Hargins, this wee farm in the front yard of his bungalow provides fresh produce for 45 nearby families, all while using a tiny fraction of the water required by a lawn. … The project has expanded to three front yard microfarms growing in adjoining neighborhoods and transformed into a nonprofit organization. …The mini farms bring environmental benefits, thanks to irrigation and containment systems that capture and recycle rain. That allows the farms to produce thousands of pounds of food without using much water.
